There will always be a place for us somewhere, somehow, as long as we see to it that working people fight for everything they have, everything they hope to get, for dignity, equality, democracy, to oppose war and to bring to the world a better life.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
